Shape shifting black object with strange lights and reflections.

I have a fourth floor balcony that faces west. Today I was enjoying the beautiful weather when I observed something coming from the west. At first I thought it was a helicopter. But as it got closer I could tell it wasn't a helicopter or a plane, so I thought it might be a drone. What got me to observe it and focus on it more was when it began reflecting light on different sides of the object. I noticed that it looked to be changing shape. That's when I began recording the video. It came from the west and curved to the south at a steady pace. The object is heading south in the video. i don't know what this is, but I do know that it wasn't normal.
